（中略）
Then my mother died. Her perfect health failed her suddenly, and her decline was not long. But she suffered much, and on the last occasion of my being with her at her bedside she told me that she was very tired and had no fear of death, and would be glad to go but for the thought of leaving me in such a precarious state of health and with a mind distressed. Even then she put no questions to me, but only expressed the hope that her prayers for me would be answered and that at the last we should be together again.
I cannot say, as I might say in the case of any other relation or friend, that I had lost her.
